Given numbers are 784,131,106,910,450
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,131,106,910,450 is 15921687600.
Find LCM of 784,131,106,910,450 with Prime Factorization
| 2 | 784, 131, 106, 910, 450 |
| 5 | 392, 131, 53, 455, 225 |
| 7 | 392, 131, 53, 91, 45 |
| 56, 131, 53, 13, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 56 x 131 x 53 x 13 x 45 = 15921687600
Therefore, the lowest common multiple of 784,131,106,910,450 is 15921687600.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
784 x 131 x 106 x 910 x 450 = 4458072528000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
131 : 1, 131
106 : 1, 2, 53, 106
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,131,106,910,450, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
131:131
106:2x 53
910:2x 5x 7x 13
450:2x 3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 7 = 280
Therefore, the value for common factors is 280.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 4458072528000/(1x280)
LCM = 4458072528000/280
LCM = 15921687600
Thus, we can understand that the LCM of 784,131,106,910,450 is 15921687600.
